The incredible pedigree, combining the powerful G13 indica and energising Hawaiian Haze sativa strains, makes G13 Haze a true classic. Providing powerful relaxation for the body and an invigorating boost for the mind, there is little wonder why it was awarded best overall strain at the 2007 High Times Cannabis Cup.

Strain Effects

As you might expect of a descendant of the famous G13, the G13 Haze strain delivers a strong yet relaxing stone with a pleasing numbing effect all over the body. This is contrasted by the more stimulating, energy boosting nature of the Haze, creating a more euphoric and uplifting high. Widely renowned for its strength, with THC levels sometimes eclipsing 24%, the long lasting high comes on quickly and really lasts. CBD levels are low, generally measured well below 1%.

Growing info

G13 Haze is characterised by its compact light green buds with an abundance of bright orange and brown hairs. While plants can reach heights of over 3m outdoors this strain is still well suited to indoor setups, where an optimal height of 100cm can be achieved with occasional pruning or LST (Low Stress Training).

A slightly longer flowering time of between 12-14 weeks leads to a high yield of 550+ g/m2 under the right lighting setups, making for a rewarding grow. Given headroom and ample light this strain will stretch quite significantly during both vegetation and flowering periods, meaningthe internodal distance is quite large. This can be a real bonus come harvest time though!

Appearance and Aroma

The first thing you will notice are the furry looking bright orange hairs covering the tightly packed green buds, followed by a strong aroma of terpenes including Mycrene, Caryophyllene and Humulene accented by subtle undertones of spicy incense, citrus fruits and an earthy hop like aroma. Fresh citrus and sweet spice flavours are prevalent on the inhale, with the exhale providing a deeper and more earthy taste.

MSNL Editors Verdict

The G13 Haze strain is an undeniable classic and must try, with its powerful calming effects and enduring high delivering an unmistakable experience. Prized for its strength, this is definitely one to ease into for all but the most experienced smokers out there.

YIELD >600 g/m2
Tasting Notes

Strength, balance and depth are the words that come to mind when describing G13 Haze. The pronounced smell of the normal Haze terpenes makes way for fresh hints of citrus and pine when cracking open the bud. On inhale there is a subtle sweetness and mild spiciness, driven by flavours of cinnamon, mandarin and lemon. This is nicely balanced on exhale where the drier and earthier character of the strain makes its presence known.

  • "Long, Excellent Colas, high yielding, resinous, and beautiful strain."

    Review by

    This is a fantastic plant, well suited to commercial production. Buds aren't as dense, almost have a sativa like growth characteristic and "wispyness" to them. Smell and flavor is sweet and tropical with a little bit of spice. Very Pleasant smell during cure. Definitely a more resin producing strain. Sticks up scissors like crazy and requires an iso dunk every 3 or 4 snips. Yield was 5-6 OZ for 2' X 2' X ~3.5' foot print at the finish of flower. Smart plant, doesn't put much flowering effort into shaded bud sites. Large, long, colas, like big italian sausages. Leafs look a little "sativey" in grow habit with slender fingers. Does not smoke with a "cerebral high" like a haze, definitely more like a classic indica stone. Very strong strain and one of the stickier one's i've seen. Should have been a breeze to trim with excellent bud structure but it was so damn sticky.

  • ""potent""

    Review by

    Just a great strain, potent, tasty, resinous, grows easy, breeds well, and cures up well!

  • "Very potent"

    Review by

    So potent, one can almost taste the potency. Grows really easy, nice tight buds, and breeds well. Very euphoric high. This one is a 3 toker for a seasoned smoker. Careful, this one's a cougher.


    Review by

    Great strain ,strong smoke,big buds and easy to grow indoors or outside although mine started flowering two weeks before Xmas in Aussie which is the middle of summer but who doesn’t want early buds 10/10 to whoever made this monster.

  • "Legendary!"

    Review by

    G13 Haze is a legendary strain subject to much rumour and speculation. It has been proclaimed as the strongest strain ever created and some say it was genetically engineered by the US government in a secret CIA lab. Whether or not these rumours are true, there is no doubt that this is one of the strongest strains available today with very high levels of THC and buds glistening with resin

  • "Too much indica"

    Review by

    Has 'haze' after it so I thought it'd be like other hazes - really uplifting, energizing, etc. It's not. Great if you need to fall asleep, but I'll move on to other hazes to get me thru the day.

  • "Don't go too fast"

    Review by

    Smoked too much and didn't get off my couch for the rest of the day. This is one where you've gotta go slow

  • "Really good, other hazes are better though"

    Review by

    I don't want anyone thinking I don't like this strain, because I really like it a lot. The four stars is only because for me, there are better hazes out there. Super Silver, for instance.

  • "I challenge the strongest"

    Review by

    There's no doubt that this is strong stuff, k? I just don't know about the strongest. I've had some THC Bomb that would for sure give it a run for its money.

  • "luv it"

    Review by

    all i smoke is haze man it's my best weed g13 amnesia super silver all basically the same - perfection

  • "Best weed ever"

    Review by

    I'm in the UK and this is by far the best strain I've ever smoked. Lots of sativas are around, but this tops the cake and is just brilliant.

  • "Chunkiest strain i've ever grown"

    Review by

    Chunky chunky chunky! The buds were huge and dense and broke up beautifully. And the smoke? Forget about it, you'll soon forget everything anyway hahaha

  • "a nice hybrid"

    Review by

    this is a mix of two of the best strains out there, an the high is phenomenol. Spicy at first, but gets sweeter, and then so sah-weet!

  • "Wow "

    Review by

    This strain knocked me on my butt!! very potent and smells great gonna do this one again for sure! It's deff a strain you want to keep around

  • "Strain will blow your mind"

    Review by

    This bud is intense, I definitely recommend you take it easy after smoking. I had one hit off my bong and while I could still do stuff for the first few minutes, the indica hit me pretty hard after that. Go easy, my friends. Go easy.

  • "Truth"

    This strain is the real deal!
